Decodo vs MarsProxies: four residential bundle edges change the answer

Decodo and MarsProxies change residential price order four times before Decodo keeps the lower checkout through 1,000 GB. Decodo is cheaper at 1 and 2 GB, MarsProxies at 5 GB, Decodo at 10 GB, MarsProxies at 20 GB, and Decodo from 50 GB onward. The sampled crossing brackets are 2 to 5, 5 to 10, 10 to 20, and 20 to 50 GB. Pair analysis dated 2026-07-26

Every sampled checkout

At 2 GB, Decodo costs $11.25 against MarsProxies at $21.95, so Decodo is the lower checkout. At 5 GB, MarsProxies remains at $21.95 while Decodo requires $35, changing the conclusion to MarsProxies. At 10 GB, Decodo still costs $35 while MarsProxies moves to $39.90, returning the lower checkout to Decodo.

The two later changes have smaller gaps. At 20 GB, MarsProxies costs $74.80 against Decodo’s $81.25, a $6.45 difference. At 50 GB, Decodo costs $150 against $159.50, a $9.50 difference. Decodo remains cheaper at the sampled 100, 250, 500, and 1,000 GB points, although the gap narrows again to $100 at 1,000 GB. A 20 GB or 50 GB buyer should verify the live tier because a small plan-price change could reverse the recorded order.

Why the winner alternates

The engine charges the entire cheapest published tier that covers the request. MarsProxies covers 5 GB with a $21.95 purchase, while Decodo’s covering 10 GB tier costs $35. At 10 GB, MarsProxies opens a $39.90 tier and Decodo’s checkout stays flat. The same pattern repeats at 20 and 50 GB as their tier boundaries arrive at different rungs. No price is interpolated between sampled volumes. Dataset method dated 2026-07-26

The purchasing models are also different. MarsProxies records a non-expiring, account-wide pooled balance with no recurring commitment. Decodo’s covering plan from 2 GB upward is a monthly bandwidth plan. Its captured row does not publish traffic expiry or rollover on the provider’s page, so this data cannot say that unused Decodo traffic survives the billing period. A buyer carrying traffic between months should treat that missing term as unresolved rather than equal to MarsProxies’ published non-expiring balance.

Published controls differ

MarsProxies publishes rotating and sticky modes, sticky sessions up to 10,080 minutes, and country and city targeting. It does not publish a concurrency maximum, state targeting, ZIP targeting, or ASN targeting in the captured row. Decodo publishes rotating and sticky modes, a 30-minute sticky maximum, and country, state, city, ZIP, and ASN targeting. It does not publish pooling or a concurrency ceiling in the recorded fields.

Those controls can change the shortlist. At 5 and 20 GB, where MarsProxies has the lower checkout, a workload requiring ZIP or ASN targeting lacks a published control in its captured row. At 10 GB and from 50 GB upward, where Decodo is cheaper, a workload that depends on a non-expiring pooled balance lacks the equivalent published Decodo term. Captured plan data dated 2026-07-26

Decision rule

Use MarsProxies for the price shortlist at the sampled 5 GB and 20 GB points. Use Decodo at 1, 2, 10, 50, 100, 250, 500, and 1,000 GB. Near 20 or 50 GB, recheck both live tiers and decide whether non-expiring pooled traffic or Decodo’s additional published targeting controls matter more than the small checkout gap.
